ALLEN H. JETEB, OF NEW YORK, N. Y.

SKYLIGHT.

To all whom it may concern:

Be it known that 1, ALLEN H. JETER, a citizen of the United States, anda resident of the city of New York, State of New York, have invented anew and useful Iniprovement in Skylights, of which the/following is aspecification.

My invention relates to roof constructions of glass and particularly tosky-light constructions.

It has for its object to produce a construction that will protect theglass plates from breaking and which will at the same time prevent anyleakage of the roof construction and the sky-light.

In an embodiment of the invention a means is provided for securing andyet allowing the expansion and contraction of the supporting beams, ameans is also provided for the protection of the glass plates and fortightly closing the roof and skylight, a means is also provided forcollect ing all the water that may be condensed on the under surface ofthe glass and also col lect all water that may leak through or be forcedor driven between the joints of or cracks of the construction.

One form of construction containing the invention is provided with ameans which will not only cushion the glass but will also .-preventleakage and will collect all the water condensed or forced into theconstruction and direct it into an open and unobstructed trough. v

The invention may be contained in a number of constructions. One of suchcon structions is shown in the drawings. The same is describedhereinafter to show how a construction embodying the invention may bemade and to show that the invention when so embodied is operative.

In the figures of the drawings, Figure 1 shows the supportingconstruction for the sky-light. Fig. 2 illustrates a cross section of anastragal used for supporting the glass panels. Figs. 3 and -l show themeans for supporting the ends of the. astragal. Fig. 5 is a longitudinalsection through the supporting housing shown in Fig. 4. Fig. 6 is amodification of the invention.

Referring to Figs. 1 and 2, 1 is the astragal supported on the curb 2 ofthe roof of the building and the ridge 3. l and 5 are the means forsecuring the astragal in position and vet allowing free movement of theparts of the sky-light caused by the shaking Specification of LettersPatent.

of the building and the expansion and contraction of the astragal andsuch other parts to which it may be connected or by which it may besupported, due to heat.

The astragal consists of a trough the interior of which is practicallyunobstructed in order that the collection of water may be facilitatedand which can be painted easily for the prevention of rust. The trough 6has a flat bottom 7 so that it can be, if desired, laid on another beamthat may be contained in the structure in which the skylight is built orlocated. It also permits the free flow of the water collected. Ifdesired it may be provided with flaring walls 8. It found preferable tomake the walls flaring in order to receive the water delivered from thecross troughs 10 located at the ends. of the plates of the glass whichcollect the water drained from the bottom of the plates or that may beforced into the interior of the building at the joints or cracks between the adjoining ends of the plates.

Brackets 11 are secured at intervals along the trough. The legs of thebrackets are socured to the walls 8 by means of rivets or screws 19. Thebrackets are angled inward as at 13 which not only makes them strongsupporting structures but also they permit the cross trough to be placedat any points or the bracket-s may be placed at any points withoutrespect to the location of the ends of the plates where the crosstroughs are located.

A T-beam 14 is supported on the brackets, the cross web being secured tothe brackets by means of rivets or screws 15. The edges of the glassplates 16 of adjoining panels extend over the cross-web of the T-beamand side portions of the glass plates of considerable width. are locatedabove the cross-web and are supported on the cross-web giving larIgebearing surfaces for the plates.

lead cushioning aprons 17 formed of strips of considerable width arelocated between the edges of the glass plates and the two webs of thebeam. The aprons extend from a point slightly above the upper surfacesof the glass downward along the central web of the beam and then overthe upper surface of the cross-web on both sides of the central web andthen down to a point slightly below the lower surface of the cross-web.The upper edges of the aprons on the plate sides by reason of the natureof the metal of which they are constructed II": 1 Jud soon extends orhangs over the upper corners of the edges of the plates. The aprons arethus so constructed that they will very perfectly cushion the glassplates. The corners of the glass plates are separated from the iron,contact with which would cause their fracture upon the slightest jar orvibration of the building. The aprons extend vertically downward betweenthe lateral edges of the plates and the beam and then over the uppersurface of the portion of the beam on which the plates rest forming awide cushion extending the full length of the panels on which the platesare supported. The plates thus safely withstand any pressure orvibration of the structure.

-'.lhe aprons extend below the lower corners of the cross-web of thebeam and thus deliver any moisture that may be collected from the underside of the glass plates directly into the trough and prevent any of itfrom running back of or up into the crack formed between the aprons andthe surface of the beam by capillary attraction. The wide contactsurface between the plates and the aprons and between the aprons and thebeam prevents leakage of any kind and as they extend the full length ofthe astragal, they seal the roof making it practically air tight. Screwbolts 18 are located on the top of the central web of the beam 14: andat intervals along the beam. A sheet metal cap 9 is located above thebeam and is placed over the bolts which pass through holes formed in theelastic cap 9. The. edges of the cap 9 rest upon the glass plates. Thecap is compressed by means of the nuts 20 which are screwed onto thebolts 18 thus pressing the edges of the cap against the surfaces of theglass plates. The caps 19 shelter the beam and assist in holding theplates against the cushion aprons 17. The ends of the astragal aresupported in housings 1' and 5 located on the curb or on the ridge orother part of the roof. The upper end of the astragal is supported inthe housing 5 which is secured in this case to the ridge 3 of the roofof the building. This is shown in section in Fig. 3. The trough 6 isplaced on the bottoms of the housings i and 5. The upper end of thetrough is provided with elongated indentations or recesses 22.Round-pointed screws extend through the walls of the housing 5 and intothe elongated recesses 22. The screws hold the trough in the housingsufiiciently tight to prevent any looseness of the beam and yet allowfor the expansion and contraction of the astragal due to heat andvibration of the building with respect to the astragal supporting theglass plates 'and thus prevent communication of the vibrations andjarring of the plates. The astragal rests and abuts on and in thehousing -l located on the curb 2 of the roof. The

ing by means of the screws 28 which pass through the side Wings- 34 ofthe housing. In order to collect the moisture that may be condensed onthe under surface of the lowest plates of the glass panels the sheetmetal piece 27 may be provided with openings 34:

An apron 26 covers the which will allow the water to drain down on tothe apron 26. v

The housing 4; extends well up under the trough 6 and over the curb. Itis made up; of the bottom 29, the side walls 30 and the end plate 31.The ends of the beam 14 and the trough 6 rests against the end plate 31.

The end plate also closes the end of the cap 19. The plate 31 isprovided with a tongue 32. The tongue 32 has a rounded substantiallycylindrical under surface which forms the undersurface of the baseportion which is of considerable dimensions while the upper surface ispyramidal, the apex of the pyramid being on the inside surface of theplate. This produces a tongue of considerable s'trength. The tongue isconstructed not only so it will have considerable strength, but alsopermits the astragal to be inserted first in the housing 4 at an angleto the bottom of the housing and the upper end of the astragal may bebrought down to and dropped into the housing 5 and secured in positionby means of the screws 23 suf iciently to prevent looseness of theastragal and yet permit the vibration of the supporting structure andexpansion and contraction of the astragal and of the supportingstructure.

The plate 3 1 is also provided with holes 35 which are located at thebottom of the channel iron 39 is located on the brackets 37. The edgesof the side walls of'the channel iron are provided with lead cushioningdevices 40. The channel iron is secured by means 'of bolts 43 whichextend upward from the brackets 37. A lead ferrule 41 is placed over thebolt 43. The plates 42 rest upon the lead cushioning devices 40 and arelocated upon opposite sides of the bolt 43,

:m-raaac the ferrule 41. being placed between the plates preventsbreaking of the plates, by striking or pressing against the bolts. A capis placed over the bolts 13, the bolts passing through holes formed inthe cap. The edges of the cap are pressed against the upper surface ofthe plates and the cap is held in position by means of the nuts 46. Thetrough 6 collects the moisture from the plates in. the manner well knownin the art and delivers it through the holes located in the housing I.The astragal, a section of which is shown in Fig. 6 is secured in thestructure in substantially the same way that the astragal shown in Fig.1 is secured.

A great many structures may be made by those skilled in the art whichmay differ greatly from the structure that I have illustrated anddescribed and yet such structures though diil'erent may still contain myinvention. The features of such constructions are described genericallyin the claims and the equivalents of such features are contemplated asbeing within the scope of the claims.

What I claim is new and desire o secure by Letters Patent as follows:

1. In an astragal for sky'lights the combination ot'atrough, housingslocated at the opposite ends-of the said trough for sup porting the saidastragal, the upper end of the said trough having elongated indentationslocated on the outside and on opposite sides of the said trough, screwsadapted to 85 extend into the said indentations and frictionally engageopposite sides of the said trough.
